The shape of the bowl, the gilding inside, and the length indicate that this is an egg spoon. The Gordian knot pattern has been popular in France since the 18th C. This particular example has additional floral engraving on what is usually a sober design.
Your spoon is earlier than you have thought. The maker, Nicolas Vautrin, specialized in small tableware, worked in Paris at 21 rue des Quatre-Fils. He first registered his mark 5 September 1844, erased 4 August 1859. His symbol was 2 stars with a crescent over the top one, and a pellet between the initials NV.
See Arminjon, v. II, no. 03355, p. 305.
